| When changing from traditional production systems to
IT-based production systems the introduction and usage
of metadata is unavoidable. Direct access of the
information stored in IT-based systems is not possible.
Descriptive and structural metadata are the enablers to
have proper access of selected material. Metadata
does not focus on descriptive information about the
content only. It describes the usage of the material, the
structure of a program, handling processes, relevant
information, delivery information about properties, and
storage of information. The basis to achieve a complete
collection of metadata is a detailed analysis of a
broadcaster's production processes and usage cases.
A logical data model expresses the relationship
between the information and is the foundation for
implementations that enable a controlled exchange
and storage of metadata. |
